ATLANTA – Georgia’s year-old Medicaid plan is falling far short of expected enrollment numbers, according to a new report from an Atlanta-based public policy group. A year since its launch, Pathways to Coverage has only about 4,300 members, much lower than the 25,000 state officials projected and a tiny fraction of the roughly half-million state residents who could be covered if Georgia, like 40 other states, agreed to a full Medicaid expansion.
